the percentage will be rounded to 25%, 50%, 75% or 100%. The specified percen-
tage is applied each time the partition boots, thus resulting in a different value if
the working memory in the cell is different. For example, a cell in a partition
has 8GB memory and the user specifies 4GB CLM. When the partition boots
4GB of that cell’s memory will be used as CLM. Later the user shuts down the
partition, adds another 8GB memory to that cell. When the partition is booted
again, the cell now has 16GB of memory, so 8GB (50%) is allocated as CLM.
• As an absolute number (default). This can also be optionally suffixed by "GB".
The clm_value is interpreted as an absolute number of gigabytes of memory.
Numbers other than integers and halves are rounded up to the nearest 0.5GB.
For example: 2.5GB will not be rounded up. However 2.3GB will be rounded up
to 2.5GB. For example, a cell in a partition has 8GB memory and the user
specifies 50% CLM. When the partition boots 4GB of that cell’s memory will be
used as CLM. Later the user shuts down the partition, adds another 8GB
memory to that cell. When the partition is booted again, the cell now has 16GB
of memory, but the CLM is still 4GB.
-m cell:[celltype]:
[use_on_next_boot]
:[failure_usage][
:clm_value]
Modify attributes of cell(s) already assigned to the target partition. Please refer to
the explanation of the
-a option for details of the different fields in this option argu-
ment. Note:
• The use_on_next_boot field of the last cell containing core IO cannot be modified
to "n".
• If modifying the CLM value of a cell in any partition other than the local parti-
tion, it is preferable to use the
-u option.
-d cell Delete the specified cell(s) from the partition. If the cell which is being deleted is an
active cell then after the execution of the parmodify command the user must
shutdown the partition using the shutdown -R command for the configuration
change to take effect. If the -B option is also specified then the partition will boot
up to the command prompt. If the -B option is not specified then the partition will
have to be booted manually from the service processor. Deletion of inactive cells
does not require a shutdown of the partition.
A cell can be specified either in the local (cabinet# /slot#) or global (cell#)format.
For example, the cell located in cabinet 0, slot 1 is identified in the local format as
0/1 or in the global format as 1.
-B Specifies to reboot the partition now. The default is not to boot. If this option is
specified and the partition to be modified is not the local partition, then the com-
mand proceeds only if the specified partition is not active. Also this option is useful
only if the
-a option or the -d option or a clm_value has been specified.
-r cell Specifies the core cell choices. A core cell choice is a configured cell which has
attached core IO. If the core cell of a partition is deleted then the firmware will
select the first core cell choice as the next core cell. One to four core cell choices can
be specified. The first cell specified is the first core cell choice, the second cell
specified is the second core cell choice, the third cell specified is the third core cell
choice and the fourth cell specified is the fourth core cell choice. Use of this option
will override previous core cell choices. So, if the order of a given cell is changing,
all of the core cell choices should be specified in the new order.
A cell can be specified either in the local (cabinet# /slot#) or global (cell#)format.
For example, the cell located in cabinet 0, slot 1 is identified in the local format as
0/1 or in the global format as 1.
-I IPaddress Specifies the IP address that should be used by management tools such as parmgr
to address the target partition. This value must be consistent with the IP address
that is assigned to the partition once HP-UX is installed and networking is
configured.
-b path Specifies the primary boot path. path specifies a physical hardware path. Note: On
Itanium-based platforms, only boot paths of the local partition can be modified.
-t path Specifies the alternate boot path. path specifies a physical hardware path. Note:
On Itanium-based platforms, only boot paths of the local partition can be modified.
